Title: Semiconductor charge sensor
Inventor: KURIYAMA TOSHIHIDE
IPC: G01N27/414
Filed: 1982-09-14
Abstract: PURPOSE:To obtain an FET type semiconductor sensor which is operable with a high sensitivity and even on a high power source voltage. CONSTITUTION:It is assumed that the quantity of impurities per unit area of a P type low impurity density silicon substrate layer 2 is set at Pscm<-2> while the quantity of impurities per unit area of an N type low impurity density surface layer 5 at Q1cm<-2>. If the quantity of impurities in the sensor area is selected so that Q1 is slightly less than Qs, the relationship of the impurities quantity in the sensor area shifts to Q1+DELTAQ1>Qs from Q1<Qs when Q1 increases equivalently to Q1+DELTAQ1 due to a charge generated in a response film. At this point, the potential of a measuring terminal changes to the voltage of an electrode 9 from a depletion layer voltage of the N type low impurity density surface layer 5. The potential of the measuring terminal shifts to 100V from about 20V to produce a large voltage change. This enables the manufacture of a pressure sensor using as a sensitive film a film adapted to generate potential by pressure.

Title: Connector
Inventor: FUKUMOTO YUTAKA
IPC: H01R24/00
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To contract the mounting area on a substrate and dispense with an inserting and drawing space by converting the horizontal movement by a member integrated with a jack to the vertical movement of an actuator to regulate the intensity of the contact force. SOLUTION: When a slide cam 17 is moved little by little to the left, a projection 23 is also moved. When the projection 23 is moved to the left, an actuator 15 is gradually lifted up since a slot 19 is inclined. When the slide cam 17 is continuously moved to the left and the projection 23 is moved, the actuator 15 is located in the top part, and a contact 18 is laid in the state where it is nipped and closed by the actuator 15. At this time, the contact force of the contact 18 is in the highest state. Accordingly, the slide cam 17 is horizontally moved, and the horizontal movement of the slide cam 17 is converted to the vertical movement of the actuator 15 to regulate the intensity of the contact force of the contact 18 with a pin 13.

Filed: 1985-07-22
Abstract: PURPOSE:To reduce the protocol time by applying data communication based on a data corresponding to a prescribed communication destination stored in a memory in applying data communication to the prescribed communication destination. CONSTITUTION:When the transmission to a specific destination is commanded, a CPU 2 extracts a dial number corresponding to one-touch key operated from an area TLN of a RAM 3 and sends the result from a MODEM 4 via a NCU 5. When the opposite equipment makes a reply, the reception of a DIS signal is awaited, and when the DIS signal is received, whether or not the communication is that using a facsimile communication network is discriminated. For example, in case of the communication using the facsimile communication network, the NSF information of a called station stored in an area SIG in the RAM 3 is extracted and set to a prescribed area, then a DCS signal is sent and the communication is controlled based on the NSF information extracted from the RAM 3. Thus, the protocol time conducted between the data communication equipments is reduced.

Title: Steel quenching method
Inventor: TAKEUCHI ATSUSHI
IPC: C21D1/06
Filed: 1979-12-11
Abstract: PURPOSE: To quench steel with less internal strain by a method wherein steel is heated to a specific temperature and rapidly cooled in the atmosphere of ammonia or ammonia plus cementation and reduction gas while controlling ammonia gas supply.  
     CONSTITUTION: A quenching treatment with less internal strain is performed for the surface quenching and hardening of steel machine parts, etc. This treament utilizes a phenomenon that the steel surface is nitrided to lower A 1 -transformation point and nitrogen is permeated into hypoeutectoid steel in austenite state, then martensite is formed under quenching. Quenching treatment atmosphere uses ammonia gas, or a mixture of ammonia and an organic liquid having cementation and reducing properties, such as alcohol, ester, and ketone, or mixture of ammonia and a neutral gas. While controlling ammonia gas supply, steel is heated to a temperature within 50°C above A 1  transformation point and then is quenched, thereby forming high-hardness martensite surface structure. Because A 1  transformation point is decreased by the nitrogen permeation, little internal strain due to hiating occurs.

Title: Packet relay system
Inventor: YOSHIDA ATSUSHI
IPC: H04L12/70
Filed: 1994-06-20
Abstract: PURPOSE:To utilize a public line effectively and to save the line utility charge by setting a line interrupt timing of a 2nd network according to a host protocol of a transmission packet. CONSTITUTION:A port number extract section 102 receiving a transmission packet outputted from a routing processing section 101 extracts a sender port number of a TCP header and provides an output to a table 103. The table 103 provides an output of a timer setting value corresponding to the sender port number to a register 104. That is, when the host aprotocol is a file transfer protocol, the line is immediately interrupted after the end of a packet to prevent useless occupancy and a timer is set to 10sec. In the case of an interactive application by a TELNET, even when end of a packet is detected, since the transmission of a succeeding packet is highly possible and a timer setting value is selected longer (60sec), the operability of using the line is improved.
